The Paris Agreement stipulates that a party “can at any time adapt its existing national contribution to raise its level of ambition.” While this does not seem to legally prevent some party from reducing the ambitions of its NDCs, most countries would consider such an approach to be different from the spirit of the Paris Agreement. On August 4, 2017, the Trump administration officially announced to the United Nations that the United States intends to withdraw from the Paris Agreement as soon as it is legally entitled to it.  The formal declaration of resignation could not be submitted until after the agreement for the United States came into force on November 4, 2019 for a three-year date.   On November 4, 2019, the U.S. government filed the withdrawal notice with the Secretary-General of the United Nations, custodian of the agreement, and formally withdrew from the Paris Agreement a year later, when the withdrawal came into effect.  After the November 2020 elections, President-elect Joe Biden promised to reinstate the United States in the Paris Agreement for his first day in office and renew the U.S. commitment to climate change mitigation.   Unlike the current UNFCCC transparency system, which sets different requirements for developed and developing countries, the new transparency framework will apply to all countries, but will provide “integrated flexibility” to meet different national capacities. The goal is to ensure that all parties meet the same standards of accountability as they do to build capacity over time. The Paris Agreement, drawn up for two weeks in Paris at the 21st United Nations Conference of the Parties (COP21) on Climate Change (UNFCCC) and adopted on 12 December 2015 marked a historic turning point in the fight against global climate change, as world leaders representing 195 nations agreed on an agreement containing commitments from all countries to combat climate change and adapt to its impact. On June 1, 2017, President Trump announced his intention to withdraw the United States from the agreement. In response, other governments have strongly reaffirmed their commitment to the Agreement.
U.S. cities, states and other non-state actors also reaffirmed their support for the agreement and promised to further intensify their climate efforts. The United States officially withdrew from the agreement on November 4, 2019; withdrawal came into effect on November 4, 2020. President-elect Biden has promised to reinstate the Paris Agreement after taking office. President Trump is pulling us out of the Paris climate agreement. In the end, all parties recognized the need to “prevent, minimize and address losses and damages,” but in particular any mention of compensation or liability is excluded.  The Convention also takes up the Warsaw International Loss and Damage Mechanism, an institution that will attempt to answer questions about how to classify, address and co-responsible losses.  InDCs become NDCs – nationally determined contributions – as soon as a country formally adheres to the agreement.
